Seven size matches point to possible packaged PE counterparts

Seven ZLIB-containing objects report expanded sizes matching separately listed Windows executables and DLLs, making them candidate packaged forms rather than confirmed identical files.

A compressed object submitted as launch.exe is reported to expand to 176,386 bytes—the exact size of a separately listed Windows executable, ntmstart.exe. The same pattern recurs across six other compressed records and their possible executable or DLL counterparts. Are these additional components, or different representations of the same underlying files?
